Detailed introduction

Simplified cost models for prefeasibility mineral evaluations

In this U.S. Bureau of Mines report, mine and mill cost models are presented to make quick estimates of the cost to develop mineral deposits in the desert region of the Southwest United States. Regression analysis was used to generate capital and operating cost equations for each model in the form Y = AX', where Y is the cost estimated and X is the assumed daily capacity in short tons.

What is the Cost of Mining Gold?

Typically, it is a lower cost mining method, meaning lower grades of ore are economic to mine. Underground mining occurs when the ore body is too deep to mine profitably by open-pit. In other words, the quality of the orebody is high enough to cover the costs Get price

Overview and Mineral Resource Estimate

The mineral sorter concentrate will be blended with the crushing circuit fines to feed a ball mill (6,700 tpd) followed by conventional lead and zinc flotation circuits. The process plant will produce on average 168 tpd of lead concentrate at 62 % Pb and 687 tpd of zinc concentrate at 58% Zn. Get price
